Good questions receive this badge. It takes multiple revisions and constant work to make a question that is universal enough to receive 25 upvotes from your peers.
How to achieve this trophy
Ask a question that attracts enough upvotes from the site's users to get a score of 25 (score being the difference between up- and downvotes).
Tips and Tricks:
Your question should be interesting to many users to attract this many votes.
Constant editing and improving your question will get it more and more attention.
Continually add the results of your progress towards an answer into your question instead of writing it as one huge log. It should be written in a manner that makes it easy for the reader to understand (as concise as possible).
Use the social media buttons (currently Twitter, Google+, and Facebook are supported) to get your question out to the wider community.
